Great job so far. Nice rail work.
I've tried smaller boxes and rails a bit last season never really got the hang of it. I built a small rail to practice on over the summer and thought I had it down. I could ollie on to the rail and balance and 180 off in my basement. when it came to actually doing it on the mountain...totally different feel. Though I don't think the training was a bad idea just need to practice more on the real thing.
